Abstract

The utility model provides a combination block of piezoresistors. The bottom of the cylindrical block used to be combined into a resistor is a semispherical inner concave body, and the upper part is a semispherical outer convex body corresponding to the semispherical inner concave body. Through such an arrangement, when combined into a piezoresistor, multiple cylindrical blocks can be superimposed and combined through the corresponding matching structure of the inner concave body and the outer convex body, which not only increases the contact area between the blocks, but also reduces the resistance, improve the performance of the piezoresistor, and make the whole combination more stable.

Description

Varistor Combo Blocks

technical field

The utility model relates to a piezoresistor element, in particular to a piezoresistor combination block.

Background technique

The piezoresistor is the main component used in lightning arresters and other equipment. The traditional piezoresistor is composed of multiple cylindrical blocks superimposed and combined, and the traditional cylindrical blocks are planes above and below. When assembled, the upper and lower planes are the same. Stacked and combined, the planes of this combination are easy to slide, and the contact area of the combination is limited, which will affect the contact resistance and fail to optimize the overall performance of the varistor.

Contents of the invention

The utility model provides a piezoresistor combination block, which has the characteristics of enlarging the contact area and reducing the resistance, improving and optimizing the overall performance of the piezoresistor, and making the assembled piezoresistor more stable as a whole.

The utility model includes a cylindrical block of an electrical assembly block, and the adopted technical scheme is: the bottom of the cylindrical block used to be combined into a resistor is a semi-spherical concave body, and the upper part is correspondingly matched with the semi-spherical concave body semi-spherical convex body. The cylindrical block used to be combined into a piezoresistor is set as a hemispherical inner concave body at the bottom, and a hemispherical outer convex body corresponding to the hemispherical inner concave body, that is, the lower concave body at the bottom and the upper one The convex body can be anastomosed to form a whole.

The utility model adopts the above-mentioned technical scheme, and because the upper and lower sides match each other, when combining piezoresistors, multiple cylindrical blocks can be placed correspondingly, so that the overall structure after the combination is stable, and the inner concave and outer convex The contact area between them is greatly increased, so that the contact resistance can be reduced, which solves the problem that the upper and lower planes of the piezoresistor block are easy to slide and cannot reduce the resistance. It has a scientific structure design, which is beneficial to improve the performance of the cylindrical block and improve and features that optimize the overall quality of the varistor.
